The Lowdown
Hey crew, Rusty here. Let’s break down the next two weeks for Kennebunk Beach.
Right off the bat, we’re looking at a long dry spell. For over a week, it’s mostly tiny, bumpy, cross-onshore junk with combined swell energy barely getting out of the double digits (under 120). The water temp is sitting about normal for this time of year, but you won’t be worrying about that because you won’t be riding much. There is one glassy morning on Saturday the 29th and another on Tuesday the 1st of September, but the swell is only about 2ft and totally gutless. It’s a solid stretch of beach time, not surf time.
The first legit opportunity rolls in on the morning of Thursday the 3rd of September. Glassy early, and we’ve got head-high plus swell at 1.9m out of the ESE with a short 8-second period. The energy hits 487 – moderate and punchy. It’ll be a bit walled-up but fun on a peak if you’re first out. This is the best window in the whole 16-day forecast hands down, but you gotta get on it before the afternoon wind turns it to mush.
Friday the 4th is another good call for the early crew: clean offshore wind from the ENE, with waist-to-chest high 1.0m groundswell from the SE. The period is a long 14 seconds, and the energy is solid at 680. That means longer waits but way more push when it comes. This is proper wave shape, but it’s better for reef or point setups than a straight beach break – expect it to run a little fast and steep. Also, keep in mind crowds are possible here.
Saturday the 5th gives us another clean, offshore morning. Swell holds at chest-high (1.2m from the ESE, 10 seconds) with good energy (560). Tide dependent, it should be peeling nicely before the onshore wind kills it after lunch.
After that, things trail off. The second week brings smaller surf, onshore winds, and energy numbers dropping fast – under 300 by Sunday the 6th, and barely a whisper by the end. Typical late summer slowdown.
Honestly, on the windy, choppy afternoons this setup looks more interesting for kite surfing than paddle surfing. But if you pick your mornings – especially Thursday the 3rd – you can still get a fun wave.
Rusty out.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
